The X-Files
Tithonus (6x10)
:
Assistant Director Kersh tries to tear Scully and Mulder apart when he partners Scully with a New York agent investigating Alfred Fellig, a freelance police photographer who conveniently shows up to document the scene of a death as soon as it happens.
While the young hotshot agent is convinced that Fellig is murdering the people, Scully has other (paranormal) theories.
